Power Network Topology Modelling Method Based On Cim

IEC61970 adopts CIM/SVG as the standards of graphic modelling for the power system, but its application is only limited in graphic integration and static topology expression at present. This paper proposed a new topology generation and searching scheme based on CIM which can reflect the actual power network diagram. The method avoids directly searching on the diagram file which is the bottleneck restrictions of this system. The system makes SVG operation program no longer as an independent system, but as the data source of the power network topology. This paper also put forward a new data structure based on this topology method, which makes searching algorithm more real-time and reliable than the traditional method.
